Psychometric Validation of Senior Perceived Physical Literacy Instrument

Abstract

Aim: To validate the Senior Perceived Physical Literacy Instrument (SPPLI). 

Methods: In the pilot study, we refined the Perceived Physical Literacy Instrument (PPLI, Cronbach’s α = 0.94, initially designed for adults) into SPPLI using internal reliability, content validity, and construct validity results. A total of 341 older adults recruited from community centers in Southern Taiwan participated in the study. A principle component analysis (PCA) identified three components of SPPLI. 

Results: Eleven items were captured from the 18-item PPLI as the SPPLI (Cronbach’s α = 0.90). SPPLI exhibits three components: attitude toward physical activity, physical activity ability, and sociality around physical activity. Significant differences were discovered in physical activity ability by educational attainment (p < 0.05) and in all three components by stage of exercise (maintenance vs. non-maintenance) (p < 0.05). The SPPLI possesses proper reliability and validity to assess physical literacy among older adults. 

Conclusions: This instrument is suggested for physical literacy assessments in physical activity programs to assess the needs of older adults and/or the effectiveness of an intervention program that aims to improve the attitude, ability, and sociality of physical activity.
